Air Pollution Control
San Joaquin Valley residents could see EPA act by Sept. 30
The agreement would set a firm date for EPA decisions on California ozone revisions that have been waiting in the federal queue. Those rules govern penalty fees and backup measures for the region’s air plan.
The proposed consent decree would not itself rewrite California’s air rules. It would require EPA to take final action on the San Joaquin Valley ozone-related submissions by Sept. 30, 2026, if the deal is approved.
- EPA would be bound to deadlines for final action on California ozone-plan revisions.
- The settlement covers penalty fee rules and a contingency measure plan for the San Joaquin Valley.
- Public comments are due July 6, 2026.
- The proposal does not itself change the air rules.
- For people living in California’s San Joaquin Valley, the question is whether federal air-quality decisions keep drifting or finally land on a date
For San Joaquin Valley residents, the issue is whether EPA will finally act on California’s ozone submissions on a fixed schedule. A proposed court agreement would require the agency to make final decisions by Sept. 30, 2026, without changing the air rules themselves.
The proposed settlement would not rewrite the air rules on its own. It would require EPA to act on revisions covering the San Joaquin Valley Unified Air Pollution Control District’s penalty fee program rules and a separate contingency measure plan for the 2008 and 2015 ozone national ambient air quality standards, or NAAQS.
The air-plan pieces on the clock
The revisions at issue include District Rules 3172 and 3173, which deal with federally mandated ozone nonattainment fees for the 2008 and 2015 8-hour ozone standards. The decree would also cover California’s Ozone Contingency Measure Plan, another part of the valley’s ozone framework.
EPA says the deal would resolve all claims by establishing deadlines for those final actions. Under the proposal, the agency would have to sign final rules by September 30, 2026, and send them to the Federal Register within 15 business days of signature.
Why the date matters
Ozone is the summer smog pollutant that can make breathing harder, especially in places that already battle stagnant air. In the San Joaquin Valley, these revisions are part of the machinery that keeps state and local clean-air obligations from slipping out of reach.
The public still has a chance to weigh in before the decree becomes final. Written comments are due July 6, 2026.
